To solve the problem that ejecting operation of liquid detergent from a liquid detergent container to a washing tool is a bother because the ejecting operation requires both the hands of the user, and that a container that can be handled with a single hand of the user includes an upward protruding main body that is an obstruction to the user and has a very complicated structure, resulting in a tendency of a high price because of a support means and a pump mechanism.

There is provided a new liquid detergent feeding device 100 consisting of a grip section 2, a container 1, and a pressing section 4. The grip section is arranged on an upper surface of the liquid detergent feeding device 100, and functions to mount the liquid detergent feeding device 100 onto a water pipe 8a of a faucet 8. The pressing section is arranged on a lower surface 1d of the container 1, and formed of a cap 4d and a spring 6. Then by pressing the cap 4d of the pressing section 4 with the washing tool 9 gripped by the hand of the user, the liquid detergent 13 filled in the container 1 is ejected from an ejection hole 1a to the washing tool 9, and then the user washes dishes etc.
